SHINGLE CLAMP.

Application filed July 29. 1922. Serial No. 578,3S0.

To all whom it may concern Be it known that I, JOHN. A. 'lorrmo, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois. have invented certain new and useful 'linproveinents in Shingle Clamps, of

which the following. is" a specification.

This invention relates to shingle clamps. it is an improvement upon the clam d1sclosed in my co-pending application terial" No. 453,434; filed March 18, 1921.

. One ofthe objectsof this invention is to provide an improved method 'ofsecuring shingles in place. u l

Another object is to provide an improved. clam for anchoring the base of butt ends of Ys ingles Without bending or perforating the same.

Another object is to provide a clamp which will allow the shingles to lie flat. Another object is to provide" a clamp which will not materially elevate any part of the shingles of one course from those of a precedingcourse or from the roof.

Another object is to provide a clamp ha ing a socket for receiving and anchoring the butt endof a shingle.

Another object is to provide a clamp which may more accur'ately'tit a shingle.

Another object is to provide aW-lamp wvhich will assist in the proper laying of shingles.

Another object. is to provide a clamp espe cially adapted for use with shingles made from relatively soft .and flexible material.

Another object is to provide a clamp which Will hold shingles securely in lace.

Another object is to provide a 621mg which is simple. reliable, inexpensive an ea to apply.

ther objects and advantages will here A inafterappear.

Embodiments of the invention and its application are illustrated in the accom panying drawing, Wherein- 4 Fig. 1 is a perspectivebf a clamp from one side.

Fig. .2 is a the reverse side.

Fig. 3 is a section on the line 3-3 of Fig. 1. i

Fig. 4 shows one type of blank from I which a c-lamp may be formed.

clamps 14.; t

erswct-ive of a clam" from Fig. 6 is a similar View of a. section of shingles showing a different Way of using the clamp.

Figs. 1 to 3 show the construction of the preferred form of clamp. The clamp may be made in one piece from a relatively thin and narrow strip of suitable sheet metal such as copper, galvanized iron or zinc. The strip is folded upon itself at the required distance from each end so as to form an interconneotin body or yoke 6 and a pair of legs 7 an 8 extending at an angle therefrom. The legs and yoke may form a substantially U shaped structure. Thelegs are not folded tightly against the body or yoke but are left spaced awaytherefroin and substantially parallel to the plane thereof. The metal forming the folds in the'strip-therefor provide a pair of corn verging abutments or seats 9 and 10 and with the legs and yoke form a pair of stirrups or sockets for receiving the edges of a shingle. If desired, holes may be paid vided in the yoke or legs for receiving nails or other fasteningnieans for anchoring the clamp in place. as will be hereinafter described.

The legs and yoke may be strengthened and made more rigid by stamping small beads 11 therein, if desired. v

Fig. 4 shows a flat blank which may be bent to form a clamp. 'Converg'ing grooves or beads 12 serve to facilitate the r0 er folding of the metal strip, either at t e tactory or at the location of use, to rovide the desired conver in seats and poc *ets be tween the legs an yo e.

Figs. 5 and 6 each show a part of three courses of shingles. The butt of shingles 13 of the top or third course are held by osejof shingles 15 of the second course by clamps 16, and those of shingles 17 of the first course by clam s 18. The clamps may be all alike and the astening means for the clamps of one course of shingles assistin holding in place the shim gles of the preceding course.

According to .Fig. 5 the clamp is applied with the yoke exposed and the legs covered by the shingles of a succeeding course. Its legs are secured by suitable means such as nails 19, at proper intervals, to the roof or wall or through the preceding shingles near adjacent corners. The legs lie flat against the roof, wall or underlying course of shingles. The yoke bridges the angle between the converging sides of adjacent shingles and lies above the same. After the desired number of clamps have been secured in place the next course of shingles is applied. The butts of these shingles are inserted under the bodies or yokes of the clamps and pushed down until their edges are firmly seated in the sockets against the converging abutments or seats. The yokes may then be given a slight blow with ahammer near or over each leg. closing the walls of the. sockets upon the shingles and firmly holding the same in place. The same procedure is re.

peated for each course of shingles untilthe roof or ivall is covered. A

According to'Fig. 6 the clamp is applidd with the legs exposed and the yoke covered the shinglese' f a succeeding course. The yoke is, in this case. nailed to the roof or wall or through the preceding course of shingles by nails QO-and lies flat thereagainst. The legs consequently lie. above the plane of the yoke and the butt ends of shingles of the succeeding course are and the converging edges are seated in the sockets against the converging seats. The legs may then be given aslight blow with a hammer and firmlyfpressed against the shingles, closing the sockets to clamp the edges of the shingles therein. y I The clamp. being made by simply bending thin strip metal, is. inexpensive to produce. The legs and yoke beingthin and lying flat do not materially raise any portion of the next succeeding course either method of application is used. The

' quite extensive surface. of the converging seats and their substantial conformity to the edges of the shingles gives good support for the shingles, serves as a ready means for properly positioning the shingles and permitsflthe use of relatively soft, flexible and slipped thereunder v of shingles Whetherrelatively inexpensive prepared shingle maicrial without danger of injury thereto. shingles of relatively soft and flexible material may he held flat on a roof or wall against the action of the Wind, etc., espe-v cially after the sockets are closed upon them.

legs of cqnal'lcngth projecting at an angle therefrom. the fold between the legs and yoke forming pockets for the edges of a sl'iingle. i

' 2. A shingle clamp comprising a relatively thin narrow strip having its terminal ends substantially parallel and folded at an angle from the body part and occupying planes spaced away from the body part to receive a shingle between the body part and said terminal ends.

3. A shingle clamp, to hold shingles on a ing a yoke member and two leg members, the legs laterally displaced from the yoke forming seats between the members for receiving the butt end of a shingle. y Y

4. A clamp for shingles comprising a strip providing a yoke with its terminals folded at angles-of forty-live degrees to form pockets, said strip creased at the point of fold to facilitate folding.

A clamp to hold shingles on a roof comprising a flat, narrow, elongated, metal strip folded near its ends to provide shinglereceiving pockets between the respective ends and the body part of the strip.
